fix(poweroutage): derive Persian dates from the naive-UTC wall-clock

Browse Source 
PowerOutageLogService called ToPersianDate on Kind=Utc values, which converts to the machine-local timezone inside PersianDateHelper. That now also happens on the DB-read path because Postgres DateTime columns are timestamptz and read back as Kind=Utc. Normalize to Unspecified first - the rule TelemetryService already applies - so the stored PersianDate does not shift with the server timezone.
